Mean volume by tax status, overall and by key demographic characteristics, was calculated using sample weights and standard errors clustered at the household-level
a Education was grouped into three categories: did not complete high school (secondary school), graduated high school, and completed technical school, university or graduate school
b Three households were missing education in 2017
c SES was determined based on an assets index developed by the Peruvian Association of Market Research Firms (APEIM). Categories A and B were combined because few households were in the highest SES (A) category (2017: 4.4%)
